I'd still want to check injector pulse. Did you use a spark tester? Some of them testers, you can open the gap, if spark will jump the gap, I don't care what color the spark, sounds strong to me. If you used a spark plug to test for spark and it was fuel contaminated, I'm not sure what color it might be?
Just to add, if you break the side electrode off a known good spark plug and the spark will jump from center electrode to side of plug, the spark should be strong enough.
